I configured this settings on my tunnel interface.

And now:

   30 second input rate 16350000 bits/sec, 12387 packets/sec
   30 second output rate 229516000 bits/sec, 23053 packets/sec

234 Mbit/sec aggregated traffic with big packet size... wow :) So the 
performance of a VAM2+ + 7201 is 35.000 packets/sec.

So thanks to everybody,  this MTU tweak is a big magic :)
